SECTION 1: FOUNDATIONS OF COMMUNITY HEALTH NURSING (Questions 1–25)
1. Which factor is most responsible for differences in an individual's health?
A) Culture of the majority of the community's citizens
B) Individual's education and income
C) Number of physicians and other health care providers in the community
D) Quality of the community health agency and hospital in the community
Answer: B) Individual's education and income
Rationale: Socioeconomic status, particularly education and income, is the most powerful
predictor of health outcomes. While access to providers and quality of healthcare facilities are
important, an individual's education and income directly influence health literacy, access to
resources, living conditions, and health behaviors.
2. What is the major goal of community health nursing?
A) To provide episodic, illness-based care to individuals in their homes
B) To preserve the health of the community and surrounding populations

C) To reduce healthcare costs through managed care systems
D) To conduct research on infectious disease outbreaks
Answer: B) To preserve the health of the community and surrounding populations
Rationale: The major goal of community health nursing is to preserve the health of the
community and surrounding populations. This is achieved through disease prevention, health
promotion, and identification of populations at risk, rather than episodic illness-based care.
3. Which of the following best defines a community in the context of community health
nursing?
A) A collection of individuals who live in the same geographic region
B) A group of locally based individuals interacting in social units and sharing common interests,
characteristics, values, and goals
C) All individuals who receive care from a single healthcare facility
D) A population group defined solely by age and gender demographics
Answer: B) A group of locally based individuals interacting in social units and sharing common
interests, characteristics, values, and goals
Rationale: A community is defined as a group of people who share something in common and
interact with one another, who may exhibit a commitment with one another and may share a
geographic boundary. It is more than just a geographic collection of individuals.
4. Which of the following best describes the primary focus of public health?
A) Diagnosis and treatment of individual diseases
B) Prevention of disease and health promotion for populations

C) Providing acute care in hospital settings
D) Conducting research on new medications
Answer: B) Prevention of disease and health promotion for populations
Rationale: The primary focus of public health is prevention—preventing disease and promoting
health for populations rather than treating individual illness. In contrast, the main focus of
medicine is diagnosis and treatment of disease.
5. A community health nurse is reviewing the core functions of public health. Which of the
following are included in these core functions? (Select all that apply.)
A) Assessment
B) Policy development
C) Assurance of availability
D) Diagnosis
E) Treatment
Answer: A, B, C
Rationale: The three core functions of public health are assessment, policy development, and
assurance of availability. Diagnosis and treatment are clinical functions, not public health core
functions.
6. A community health nurse is working with an individual who has been diagnosed with
mental illness and requires regular monitoring of medication compliance to prevent
rehospitalization. Which level of practice is this nurse demonstrating?
A) Community level

B) System level
C) Individual level
D) Population level
Answer: C) Individual level
Rationale: The Public Health Intervention Wheel includes three levels of practice: community,
system, and individual. Individual-level practice involves providing care to individuals, such as
monitoring medication compliance for a person with mental illness.
7. A community health nurse is working with the state health department and federal vaccine
program to coordinate a response to an outbreak of measles in a migrant population. Which
level of practice is this nurse demonstrating?
A) Individual level
B) Community level
C) System level
D) Family level
Answer: C) System level
Rationale: System-level practice involves working with organizations, agencies, and systems to
address health issues. Coordinating with state and federal agencies to respond to an outbreak is
an example of system-level practice.
8. A public health nurse is working with area high schools to give each student a profile of his
or her health to promote nutritional and physical activity lifestyle changes. Which level of
practice is this nurse demonstrating?
A) Individual level
